Question 1:
Write a program that initializes the 10 student scores in an array to be zero. It will ask the user to input the scores available. Note that this array of size 10 could be filled up in full or partially. A menu will be displayed afterwards, allowing the user to choose to perform one of the following functions:
1. Count the number of non-zero elements (which means the actual size of the array);
2. Find the maximum and minimum scores in the array through its reference parameters;
3. Find the minimum element among the first n elements (you should ask the user to specify the value for n first, and n should be less than or equal to the actual size of the array);
4. Find the second largest score in the array;
5. Check whether a particular score is found within the f ..

can you at least post your program codes of two questions before asking for help

这个应该是学校的程式作业吧
同唐老鸭说的，总不能重头到尾全写出来吧
虽然作业交差，可是自己学到的少之又少呢

同感+1....
程式就是要自己写过才会有经验...
刚开始一定都会很辛苦的....
像我们每次拿到作业...
就开始要构思到底要怎么写...
那是一个很痛苦的过程...
虽然有时候根本写不出来...
或是写完以后连compile都不能过....
但是老师总是说...
就算写不出来...交个尸体也好...
这样他才知道哪边我们不会....

而且...当每完成一个程式的时候...
那种高兴的感觉是无法形容的...
所以建议楼主还是先写出一些...
再PO上来跟大家讨论吧~
